Ive had Ispy setup for years, all my cameras work fine. Lately I decided to use the mobile service on chrome -> ispyconnect.com/mobile. and I can connect via my desktop, laptop and phone, but only on local wifi. I can not connect through 4G or any other mobile wifi. It seemed to work on 4G the first time I tried, and if i reset Ispy it works on 4G for a sort time, but later when I try to access the server its not working again, so I'm not sure if it was a fluke, or something wrong with my settings. and yes I have a subscription. This is a "mobile" service and your suppose to be able to view your cams away from the house, so So I'm assuming the answer is not " it doesn't work with data plans but only with your local wifi.... I used the default settings.
